I found that 99% of retail investors have a fatal bad habit: they can't hold on when prices rise, but they don't cut losses when prices fall. When prices are rising, they always think, 'I'll wait a little longer, afraid it will pull back,' and as a result, they often miss the best profit-taking opportunities; when prices fall, they always think, 'I'll wait until I break even before closing,' and end up getting trapped, continuing to wait until liquidation. After liquidation, they become relaxed, entering an endless panic, questioning themselves and even the market, from 'If only I had known, I should have…' to 'Blockchain is a scam.' Therefore, before opening a position, it is essential to clarify the operating range and plan, ensuring that losses are within a bearable range. Don't be distressed when losing; take partial profits or adjust stop losses when prices rise, especially in volatile market conditions, as this can effectively reduce risk. Blindly opening positions and holding onto losing positions will only cause you to burn out faster in the market. Watching more, learning more, and executing more is the key to surviving longer in this market.
